toUpperCase() & Concatenation in Javascript

Where did I go wrong?

app.js
var id = "23188xtr";
var lastName = "Smith";

var userName
userName = id.toUpperCase();
userName ="#"+ "lastName.toUpperCase()";
index.html
<!DOCTYPE HTML>
<html>
<head>
  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

This stumbled me for a bit also. I ended up doing the following:

var id = "23188xtr";
var lastName = "Smith";

var userName = id.toUpperCase();
userName += "#"+ lastName.toUpperCase();

Dewane's answer is also correct but you could achieve the same result with less typing as noted in this exercise.

You forgot to add id.toUpperCase to the concatenated string and remove the double quote from lastName.toUpperCase. It should look like this...

var userName
userName = id.toUpperCase();
userName = id.toUpperCase() + "#" + lastName.toUpperCase();

Dear Dewane,

Thank you-Thank you-Thank you!

I thought by assigning userName to id.toUpperCase(); already, all i had to do was add the "#" and the lastName.toUpperCase();
